aade077e43 rockchip: Move bootrom-related declarations to a header
So far spl-boards have declared the back_to_brom() function as simple
extern in the files themself. That doesn't scale well if every boards
defines this on its own.
Therefore move the declarations to a bootrom header.

739760569f rockchip: rk3288: use spl_early_init() instead of spl_init()
Use spl_early_init() to make sure that early malloc() is initialised. This
fixes booting on firefly-rk3288, for example.

427351dc1d rockchip: Fix SPL console output when ROCKCHIP_SPL_BACK_TO_BROM is enabled
Move back_to_bootrom() call later in SPL init so that the console is
initialized and printouts happen.

Currently when ROCKCHIP_SPL_BACK_TO_BROM is enabled there is no console
output from the SPL init stages.

I wasn't sure exactly where this should happen, so if we are set to do
run spl_board_init, then go back to bootrom there after
preloader_console_init(). Otherwise fall back to old behavior of doing
it in board_init_f.

c3aad6f65b rockchip: Use rockchip_get_clk() to obtain the SoC clock
The current code picks the first available clock. In U-Boot proper this is
the oscillator device, not the SoC clock device. As a result the HDMI display
does not work.

Fix this by calling rockchip_get_clk() instead.

b47ea79219 rockchip: add option to change method of loading u-boot
If we would like to boot from SD card, we have to implement mmc driver
in SPL stage, and get a slightly large SPL binary. Rockchip SoC's
bootrom code has the ability to load spl and u-boot, then boot.

If CONFIG_ROCKCHIP_SPL_BACK_TO_BROM is enabled, the spl will return to
bootrom in board_init_f(), then bootrom loads u-boot binary.

Loading sequence after rework:
bootrom ==> spl ==> bootrom ==> u-boot

2b1cdafa9f common: Pass the boot device into spl_boot_mode()
The SPL code already knows which boot device it calls the spl_boot_mode()
on, so pass that information into the function. This allows the code of
spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets
board_boot_order() correctly alter the behavior of the boot process.

The later one is important, since in certain cases, it is desired that
spl_boot_device() return value be overriden using board_boot_order().
